That's not a bad philosophy for most things, but a phone is something you use everyday. $99 translates to 95 cents per week over two years. You'd rather save 95 cents per week than have the latest generation device?
I think for 95 cents per week I'd take:
- A better camera
- Faster speed
- More software updates down the road
- Overall better experience
I also had a 3GS for 2 years until I got the iPhone 4 recently, and I think there are enough significant improvements with the iPhone 4 to justify 95 cents per week, especially since its a device I interact with daily, sometimes for several hours a day. But that's just me.
If it was something I used once a week or two, I'd totally agree. I bought a crappy toaster for ~$20 because I only make Eggo waffles in it a couple of times a week. I certainly don't do anything fancy with it, and my interactions are limited to a couple of minutes of toasting maybe twice a week.
